973980 divided by 61 
The aim is to understand the frequency of 61 in 973980.

Let's proceed to step 1:
The number 61 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 61

Going ahead to step 2:
97 divided by 61 is 1 with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 61 from 97 leaves us with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 61

On to step 3:
The number 61 fits into 363 5 times, leaving a remainder of 58.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 305 from 363, we get 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 61

Moving on to step 4:
61 goes into 589 9 times with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 159.0
The remainder is 40 after subtracting 549 from 589.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 61

Moving on to step 5:
61 can be fit into 408 6 times, resulting in a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 1596.0
If we take 366 away from 408, we end up with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 61

Advancing to step 6:
420 divided by 61 is 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 15966.0
Subtracting 366 from 420 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 7:
If we divide 540 by 61, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 15966.8
Subtract 488 from 540 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
If we divide 520 by 61, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 15966.88
If we take 488 away from 520, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 15966.88 with a balance of 0.032.
